American personal item

American’s personal item is 18 × 14 × 8 in (45 × 35 × 20 cm). It must fit under the seat and is free on every fare, including Basic Economy. You also get 1 free carry-on (22 × 14 × 9 in / 56 × 36 × 23 cm) on all fares — but Basic boards Group 9, so plan on the personal item as the reliable cabin bag when bins fill. Official examples include a purse / small handbag. Unlike United Basic Economy (personal-only on most routes), AA Basic keeps both bags free.

Personal item: always free if it meets 18 × 14 × 8 in (45 × 35 × 20 cm) and fits under the seat.

Full carry-on: also free on all fares including Basic Economy (22 × 14 × 9 in / 56 × 36 × 23 cm).

Checked: paid domestically (Main Cabin tickets on/after Apr 9, 2026: 1st $45/$50; Basic Economy May 18+ higher) unless a waiver applies — details on American baggage fees; don’t duplicate full tables here.

Free extras (not a second personal item): 1 diaper bag per child; breast pump; small soft-sided cooler of breast milk; child safety seats / strollers / medical or mobility devices.

• Soft bags that don’t fit under the seat may lose personal-item status.
• Basic Economy Group 9: AA warns overhead is usually full — pack so essentials live in the 18 × 14 × 8 personal item.
• Do not cite United’s $75 gate fee for a failed personal item / BE carry-on as an American rule — do not invent an AA personal-item gate dollar.
• Carry-on dims (22 × 14 × 9) are not the personal-item limit.
• American Eagle: larger-than-personal-item carry-ons are often valet-tagged free — the personal item is still what you keep at your seat.
• Don’t copy Delta’s “no published dims” framing — AA does publish 18 × 14 × 8.

1. Choose a bag that measures ≤18 × 14 × 8 in when packed; measure packed, not empty marketing size.
2. On Basic / full flights, keep meds, chargers, and valuables in the under-seat bag.
3. Use the free carry-on on mainline when bins allow (still free on Basic).
4. For checked fees and ticket-issue date tables, stay on the baggage fees sibling — no Amazon fee framing.

Soft picks for under-seat / American personal-item size. Prefer non-expanding backpacks and totes marketed at or under 18 × 14 × 8 in. Measure when packed.

AmazonCard — Under-seat backpack (≤18×14×8)
Daypack or personal-item backpack marketed for airline under-seat use. Confirm listed exterior dimensions stay within American’s 18 × 14 × 8 in (45 × 35 × 20 cm) when packed — especially useful on Basic Economy when overhead fills.

AmazonCard — Slim personal-item tote
Structured tote or slim shoulder bag aimed at under-seat fit. Useful when you want a purse-style personal item that still clears AA’s published size without expanding past the under-seat limit.

What is the American Airlines personal item size?

18 × 14 × 8 inches (45 × 35 × 20 cm). It must fit under the seat. Official examples include a purse / small handbag.

Is a personal item free on American Basic Economy?

Yes — Basic includes one free personal item and one free carry-on (unlike United Basic Economy on most routes). Basic typically boards Group 9, so the under-seat bag is what you can count on keeping when bins are full.

What if my personal item doesn’t fit under the American seat?

It may not count as a personal item and could need to go in the overhead (as your carry-on) or be checked. Do not invent a United-style $75 personal-item gate fee for American.

Does American allow a backpack as a personal item?

Only if it fits the published 18 × 14 × 8 in under-seat limit when packed. Official example language is purse / small handbag — stick to the size rule rather than overclaiming backpack approval beyond fit.

What’s the difference between American personal item and carry-on?

Personal: 18 × 14 × 8 in, under seat, free. Carry-on: 22 × 14 × 9 in (56 × 36 × 23 cm), overhead, also free on all fares including Basic. Full carry-on detail: American carry-on size.

How does American’s personal item compare to Delta, United, Frontier, or Southwest?

AA and Frontier both publish 18 × 14 × 8. United publishes 9 × 10 × 17 in. Delta requires under-seat fit but publishes no L×W×H. Southwest: free personal item, no published inches.
